ANTIFRIQ'I'ION ROLLER Filed Feb. 19, 1929 ATTORNEY Patented Nov. 25,1930 I v UNITED STATES FREDERICK K. KILIAN, F SYRACUSE, NEW YORKANTIFRICTION ROLLER Application filed February 19, 1929. Serial No.341,146.

This invention relates to ball bearing or antifriction rollers such asare used on the drawers of cabinets to run along tracks in the cabinetsdurin the opening and closing of the drawer an it has for its object aparticularly simple unitary roller or bearing construction by which theroller or bearing is attachable to a support.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawing in which like characters designate correspondlng parts in allthe views.

Figure 1 is an elevation of this antifriction roller and the contiguousportions of the support therefor.

Figure 2 is a vertical sectional view taken centrally on Figure 1.

Figure 3 is a vertical sectional View of one of the sections of theinner raceway.

Figure 4. is a similar view of the outer raceway. p Figure 5 is a viewsimilar to Figure 3 of the other section of the inner raceway.

Fi re 6 is an elevation of the stud.

This ball bearing roller forcabinet drawers and the like comprisesgenerally, a stud having a collar between its ends and near one end, theportion of the stud on one side of the collar constituting an axle andon the other side of the collar constituting a stem for securing to asupport, inner and outer raceways and balls between the raceways, theouter racewa constituting a roller, the in- ,ner raceway eing mounted onthe axle and abutting against the collar and the outer end of the studor raceway having means for holding the inner raceway in positionagainst the collar.

1 designates the support which may be a 1 part of, or a part associatedwith the drawer.

2 is the stud having a collar 3 near one end thereof. a

4 and 5 are sections of the inner raceway mounted on the stud or theaxle part thereof, one section abutting against the collar.

6 is the outer raceway which serves as a roller to run along the trackand 7 the balls between the raceways. The parts are held assembled byupsetting as by riveting or spinning the outer end of the stud or axle 2over onto the outer face of the inner raceway section 4 as at 8, thesection 4 being formed with a conical countersink in which the end ofthe stud is upset as by riveting or spinning. The collar 3 is ofsubstantially the same diameter as the inner raceway.

9 designates the stem portion of the stud, that is, the portion on theopposite side of the collar 3 to that on which the raceways are located,the stem extending through a hole in the support 1 and being secured tothe sup port by upsetting the end of the stud by riveting or spinninginto a conical recess in the outer face of the support.

This bearing construction is particularly advantageous in that it isextremely economical in construction and applied as a unit to thesupport for the reason that the securing means is part of the stud oraxle on which the inner raceways are mounted.

'What I claim is:

1. A ball bearing roller structure comprising a stud having a collarbetween its ends,

inner and outer raceways, the inner raceway comprising separablesections mounted on the stud on one s1de of the collar, one sectionabutting against the collar, and the outer 9 end of the stud beingprovided with means coacting with the other section to hold the sectionstogether against the collar, balls be tween the inner and outerraceways, the outer raceway serving as a roller, the portionof the studon the other side of the collar to that on which the raceways aremounted, serving as a stem to attach the roller to a [support with thecollar abutting against the support, said collar serving, to locate theraceways on the stud and to locate the stud relatively to the support,whereby the outer raceway serving-as a roller is accurately positionedrelatively to the support.

2. An antifriction bearing comprising, in combination, a stem portion, acollar formed integral with said stem portion, an inner raceway mountedon the stem portion and thrusting against one side of the collar, aroller having an outer raceway therein, and antifriction members betweensaid raceways.

3. A ball bearing roller assembly comprising, in combination, a stemportion, a collar formed integral with said stem portion between theends thereof, an inner raceway mounted on said stem portion andthrusting against one side of the collar, a roller having an outerraceway formed therewith, and ball bearings between said raceways. I

4. A ball bearing roller assembly comprising, in combination, a stemportion, a collar formed integral withsaid stem portion be,- tween theends thereof, a cone mounted on said stem portion and thrusting againstone side of the collar, a complemental cone mounted on said stemportion, means holding said cones in operative position, ball bearingsoperative on said cones as an inner raceway, a roller having an outerraceway formed therein and mounted on said ball bearings.

5. A ball bearing roller assembly comprising, in combination, a stemportion composed ofmaterial soft enough to be riveted, a collar formedintegral with said stem portion between the ends thereof, an innerraceway of hard material mounted on said stem portion and thrustingagainst one side of the collar, a roller having an outer raceway formedtherewith, and ball bearings between said raceways.

In, testimony whereof, I have hereunto signed my name, at Syracuse, inthe county of Onondaga and State of New York, this 15th day of February,1929.

FREDERICK K. KILIAN.
